"As a quick preface, the technician and service provided were good. They were on time and I am happy with the work they did. That said, I needed a new outlet installed in my garage. They were able to run the wire through the attic and did not need to mount the outlet into drywall. So, not a big job in terms of parts or labor (a bit over an hour?). They charged over $700 for the work. After asking a couple of other reputable electricians about it while they were here talking to me about another project, it turns out I paid at least double what an industry-standard rate should have been. Totally my fault for not getting multiple quotes before the original project. Another thing to keep in mind is that they charge a consultation fee to send out an electrician to provide a quote for a job. As I said, the work overall is good and I hope this is a one-off issue. That said, if you are thinking about paying Applewood to quote your project, I highly recommend you speak to a couple of other professionals first before the Applewood electrician is sent out."

"Kevin was on time, competitively priced, explained the process and was very professional. Super thorough in cleaning the dryer vent and spent a great deal of time cleaning up afterwards. Have obviously had my vents cleaned for many years, Kevin was head and shoulders above any service we have used in the past. Would highly recommend this company. Update 03/18/20 This is the third time we have had Kevin out for service/repair on various appliances, and I can not say enough good things about him! He has been punctual, super helpful explaining what needs to be done, and as others have commented on, the areas that he has worked in are all always cleaner than they were before he got there. He is super courteous, professional, and is one individual that I would recommend HIGHLY to anyone looking for home appliance repair or dryer vent cleaning."

"We had a fantastic experience with Aire Serv of South Denver when they recently replaced the HVAC system and furnace in our rental home. Steve and the entire team went above and beyond throughout the process. They were professional, knowledgeable, responsive, and kept us informed every step of the way. The installation was completed efficiently, and the quality of their work gave us confidence that everything was done right. They even provided a portable AC unit so we didn't sweat until our install date. If you're looking for a trustworthy HVAC company, I highly recommend Aire Serv of South Denver. It's clear that customer service and craftsmanship are priorities for this team. Thank you, Steve, for making what could have been a hot summer - a cool experience!"

"These guys are above excellent! I already had estimates from 2 companies for for a new furnace. One was way too high, and I just didn't feel right about the second one. I called One Hour and got an appointment for a quote the following day. Habib came and took all the measurements for the entire project and gave me an exact price for the work. He explained everything I wanted to know, including the high standards their company follows, from getting exactly the right heating capacity to the requirements for every one of their employees: from drug screening and criminal records to excellent work and cleanup. They have a great guarantee, without any of the usual "membership" stuff that many other companies have. (I asked Habib about the lower estimate from the other company, and he showed me that it was only an estimate that could change. So even though it was lower, it could have ended up being much higher.) The next day, Greg and Ryan came and installed the furnace. Wow! They came and did the work quickly, quietly, and efficiently. They cleaned up afterwards. Greg showed me the new furnace and how to use the emergency shut-offs, and how to change the filter. And he explained how to use the thermostat. I appreciate working with companies that are excellent, and I've found one here! I highly recommend them for any heating/cooling needs."

FAQs for thermostat installation and replacement projects in Denver, CO

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
